Oil saturation through four steps of simulated production showing a comparison of how host rock models with high (1000 mD) and low (150 mD) permeabilities respond to the introduction of deformation bands that are one order of magnitude less permeable than the host rock. Oil saturation through four steps of simulated production showing a comparison of how host rock models with high (1000 mD) and low (150 mD) permeabilities respond to the introduction of deformation bands that are one order of magnitude less permeable than the host rock.
